“…The percentage distributions of color blindness in the different ethnic groups and countries are found to be variable: in our study the prevalence of color blindness among the male students (8.46%) were found to be similar recorded in America, 8.0% (Mueller and Young, 1995), Tehran, 8.18% (Modarres et al, 1996), Iraq, 8.19% (Al-Amood et al, 1981), Denmark, 8.7% (Norn, 1997), Jordan, 8.72% (Al-Aqtum andAl-Qawasmeh, 2001) and India, 8.73% (Shah et al, 2013). However, the prevalence of the color blindness among male students in our present study is higher than that of Pakistan, 1.1% (Alam et al, 2008), India, 1.12% (Dakshayani and Gangadhar, 2006), 2.4% (Kalamma et al, 2008) and 2.4% (Luxmi and Kapooe, 2011), China, 3.0% (Huang et al, 1990), Nepal, 3.8 (Niroula and Saha, 2010), Philippine, 5.17% (Cruz et al, 2010) and Malaysia, 6.7% (Balasundaram and Reddy, 2006).…”

The incidence of color blindness varies from race to race and in different geographical area. Since, there is no such report about the prevalence of color blindness in the Kurdistan region (North of Iraq), the present study had been conducted to find out the incidence of color blindness among preliminary, secondary and college students of Erbil city, Kurdistan region-Iraq. Participant's (n=1856, 1275 males, 581 females, age group 7 to 25 years) color vision was tested by using Ishihara chart. Among 1275 male students, 108 students (8.47%) were found to be color blind: 42 of them showed deuteranomalia, 39 protanomalia, 20 deuteranopia and 7 protanopia. Among 581 female students, 8 females (1.37%) were found to be color blind: 5 of them showed protanomalia, 2 deuteranomalia and 1 deuteranopia. Data observed by Chi-square test showed there was no significant difference between ethnic groups of both male and female students. Studies on color blindness in Kurdistan region are very few; we hope this student-based investigation is meant to fill a gap in this field.
